I read the Sheldon Brown article sometime back in highschool (http://sheldonbrown.com/brakturn.html for anyone who is interested) and since then have configured my bikes with the front brake on the right hand. I prefer to do most of my braking with my front brakes (as I usually find that the rear brakes do very little to slow me down in comparison), and so like to be able to use my front brakes while I am signaling. I've run most of my bikes this way for years.
